Siege of Suzhou
The Battle of Suzhou was fought on 6 December 1863, between the Anglo-Qing army and the Taiping army. This battle was also for known the Suzhou Massacre, in which by the command of Li Hongzhang, 10,000 rebels were executed.
Background
By the early 1860s, the Taiping Heavenly Kingdom was declining after years of bitter fighting against the Qing Dynasty. Once the revolutionary force which had captured major territories across the Sourthen China, the rebellion was being pressed back towards the core strongholds in Jiangsu and Zheijiang. The city of Suzhou was the wealthiest and one of the most strategically vital centre in the Yangtze delta. Its fall would open the route towards Nanjing, the capital of the rebellion.The Qing sent the Huai Army under the command of Li Hongzhang, which was a provincial force consisting of 25,000 men of which 3,000 was cavalry and nearly 150 artillery pieces. Li's force wassupported by the Charles Gordon's Ever Victorious Army, with 5,000 Chinese men under the command of European officers and 6 steam powered gunboats of the Royal Navy.
Inside the city, the Taiping garrison numbered nearly 200,000 men, organized in Wan divisions. There were 14-18 wans each consisting of 12,500 men, and each having 5 banners in them. Despite their large numbers, the defenders faced shortages of food, ammunition, and modern artillery. Their morale was weakened by the steady advance of the Qing and effectiveness of Gordon's gunboats along the canals.
The Siege
In the autumn of 1863, the Haui army and the EVA under advanced steadily through Jiangsu, encircling the Taiping positions. After successful victories at Changzhou and Wujiang, Li and Gordon had reached the outskirts of Suzhou by September.October
The Huai army and EVA started blockading the city, they besieged the city. Skirmishing and raiding started happening. The EVA fleet consisting of 30-50 junked boats and 6 steamers with up to 32-pounder guns and 12-pounder howitzers, had started bombarding river outposts and took control of the canals. Li and Gordon's men also captured the Pan Gate and the Mudu blockhouse fort. This disrupted the supply lines and forced the defenders inside the second layer of walls in the city.November
By November, the siege had entered an decisive phase. The Qing forces tightened the encirclement by storming smaller canal forts and villages, while gunboats also cut off supply lines along the waterways. With outer defense collapsing, the Taiping garrison was forced to clear the walls of Suzhou and get to the citadel. At the same time, Li Hongzhang started negotiating with Tan SauGuan, offering leniency to encourage surrender. Shortages of food and ammunition, coupled with declining morale, made the resistance untenable.December
By early December, the siege had reached its breaking point. The Taiping garrison inside Suzhou was exhausted, short on food and ammunition, and morale had collapsed after weeks of encirclement and loss of outer defenses. On 6 December 1863, under negotiated terms, the city gates were opened to Hongzhang's army. Gordon assured the Taiping commanders that their lives will be spared if surrendered.Surrender
